PLTL-73 Thermal Conductivity by Differential Scanning Calorimetry (DSC)
Thermal conductivity describes the ability of a substance to dissipate heat. In general, substances with high thermal conductivities dissipate heat more rapidly than substances with low ones. Greases and oils with high thermal conductivities are used to coat heat-generating elements of electrical and mechanical systems to protect other system components from thermal damage. Greases and oils with low thermal conductivities may jacket systems to limit temperature fluctuations from external sources. This test determines the thermal conductivity of grease or oil. Petro-Lubricant Testing Labs can test temperatures from 30oC to 100oC. Other temperatures may be determined by extrapolation.
Using a differential scanning calorimeter and a specially designed, proprietary test cell, the sample is brought to the test temperature. The heat flow is followed and compared to a standard of known thermal conductivity. The thermal conductivity is reported in watts m -1 K -1. Please specify the temperatures of interest.
